cds-question@unistra.frsurveysmagellanic-cloudssupernovaephotometryWe analyze two years (mid-2010 to mid-2012) of OGLE-IV data covering ~65deg^2^ of the Magellanic Bridge (the area between the Magellanic Clouds) and find 130 transient events including 126 supernovae (SNe), two foreground dwarf novae and another two SNe-like transients that turned out to be active galactic nuclei (AGNs). We show our SNe detection efficiency as a function of SN peak magnitude based on available SNe rate estimates. It is 100% for SNe peak magnitudes I<18.8mag and drops to 50% at I~19.7mag. With our current observing area between and around the Magellanic Clouds (~600deg^2^), we expect to find 24 SNe peaking above I<18mag, 100 above I<19mag, and 340 above I<20mag, annually. We briefly introduce our on-line near-real-time detection system for SNe and other transients, the OGLE Transient Detection System.2013AcA....63....1Khttps://cdsarc.cds.unistra.fr/viz-bin/cat/J/AcA/63/1CatalogResearchIsServedByTAP VizieR generic serviceIsServedByConesearch servicerelated-toftp://ftp.astrouw.edu.pl/ogle/ogle4/transients/SN/MBR : Home Pagehttps://cds.unistra.fr/vizier-org/licences_vizier.htmlhttps://vizier.cds.unistra.fr/viz-bin/VizieR-2?-source=J/AcA/63/1https://vizier.iucaa.in/viz-bin/VizieR-2?-source=J/AcA/63/1http://vizieridia.saao.ac.za/viz-bin/VizieR-2?-source=J/AcA/63/1https://vizier.cds.unistra.fr/viz-bin/votable?-source=J/AcA/63/1https://vizier.iucaa.in/viz-bin/votable?-source=J/AcA/63/1http://vizieridia.saao.ac.za/viz-bin/votable?-source=J/AcA/63/1GETtext/xml+votablehttps://tapvizier.cds.unistra.fr/TAPVizieR/tapCone search capability for table J/AcA/63/1/table1 (OGLE-IV transients from the OGLE-IV Magellanic Bridge Data)https://vizier.cds.unistra.fr/viz-bin/conesearch/J/AcA/63/1/table1?https://vizier.iucaa.in/viz-bin/conesearch/J/AcA/63/1/table1?http://vizieridia.saao.ac.za/viz-bin/conesearch/J/AcA/63/1/table1?GETtext/xml+votable180.050000true28.6195-72.28597220.0055555555555555565/8222 8237 8239 8241 8243-8245 8248-8249 8252 6/32879 32892 32925-32927 32947 32961 32963 32968-32969 32971 32985-32990 33001-33005 33016 33066 33152-33153 33160 33300-33301 33303 33344 33347 33352 33354https://cdsarc.cds.unistra.fr/viz-bin/moc/J/AcA/63/1?format=asciiOpticaldefaultJ/AcA/63/1/table1OGLE-IV transients from the OGLE-IV Magellanic Bridge DatarecnoRecord number assigned by the VizieR team.
